Municipal Wastewater Flow and Treatment Revenues to Exceed $23 Billion In 2014
Thanks to the rapid growth in Asia, flow control and treatment revenues in the municipal wastewater treatment sector will grow to over $23 billion in 2014. This is the latest aggregation from a number of market reports published by the McIlvaine Company. (www.mcilvainecompany.com)

The biggest expenditures will be for pumps which are needed in the transport of sewage to the treatment plant, through the treatment processes, and then to move the purified water to a receiving stream. Treatment chemicals are the next largest segment. They are used in primary and secondary treatment to provide separation, corrosion control and, more recently, reduction of odors. The chemical demand is increasing due to tougher regulations in many countries.
There has been a growth in the use of cross-flow membrane technology due to the need to further purify effluent for reuse. The membrane bioreactor (MBR) usage has also grown rapidly.
The belt filter presses (one of the macrofiltration technologies) compete with centrifuges to dewater the sewage sludge. Larger plants tend to select centrifuges where smaller plants opt for belt presses. The benefits of automation of the processes are justifying greater monitoring expenditures. Smart valves are another advancement to improve plant efficiency.

Water and Wastewater Treatment Chemicals: World Market
How to Increase Sludge Dryness (Answers at WEFTEC)
WEFTEC will start on October 5 and close on October 9. McIlvaine, as usual will be interviewing exhibitors and speakers. However, a new concept will also be introduced. This concept is called the Global Decisions Positioning System™ (GDPS). The template is the McIlvaine Power Plant Air Quality Decisions. This system has been continuously honed since it was introduced in 1974. Now the concept is being applied to many other areas including municipal secondary wastewater treatment.
The concept is explained at:
Global Decisions Positioning System™ (GDPS)
Global
Decisions Orchard
Each system has a sector in the Global Decisions Orchard. Many decisions require travel through a number of decision trees. GDPS provides the route maps. Secondary wastewater treatment requires thousands of decisions and therefore thousands of route maps, so achieving drier sludge is just one of them.
Secondary Wastewater Treatment Orchard Sector
Sludge Biological Chemical
Dewatering Treatment Treatment
Sludge Drying Sludge Combustion land disposal
Wastewater plants are continually seeking to reduce energy costs through more efficient operations. Drier sludge is one potential.
Drier Sludge Route Map in Secondary Wastewater Treatment GDPS
Many plant operators and consultants attending WEFTEC will be focused on improving the efficiency of their plants. Reducing aeration energy with variable speed drives or more efficient blowers may be an option to be investigated. Automating operations would also be attractive. Energy recovery by generating biogas would be another. A fourth option would be obtaining a drier sludge to reduce incinerator fuel consumption.
Each opportunity needs to be investigated separately. We have chosen the drier sludge on which to focus instead of spending hours determining which speeches, posters, and stands will provide insights on each aspect of the investigation, the visitors can use the equivalent of your automobile GPS. The advantage will be as significant as the GPS system in the vehicle vs. the map provided at the rental counter.
To investigate ways to obtain greater sludge dryness it makes sense to first see whether there are some operating initiatives which will achieve the improvement.

Water & Wastes Digest- Booth 907 – The current Issue of Water Wastewater Digest shows how MSD Chicago is improving sludge dewatering and reducing energy consumption “Currently, the solids removal process at Stickney WRP is undergoing a major upgrade, according to MWRD Executive Director David St. Pierre. “The primary sludge and waste-activated sludge streams, which are currently combined, are being separated for more efficient thickening prior to digestion. Primary sludge will be thickened in a new facility that houses eight 80-ft-diameter gravity concentration tanks with a biofilter for odor control. Waste-activated sludge will be thickened in 16 new high-tech centrifuges that have nearly three times the throughput and require half of the power draw as the centrifuges being replaced,” St. Pierre said.

Sludge Dryness GDPS Route Map will be Permanent
This route map will be continually expanded to cover the full range of activities relative to obtaining drier sludge. It will be one of many routes in the municipal wastewater secondary treatment GDPS. This system will be available free of charge to any municipal wastewater plant employee in any country. There will be a subscription fee for others. Contact McIlvaine for the details.
Some WEFTEC Highlights:
ANDRITZ developed a patented optically based process control system that works without direct contact with the sludge. Infrared sensors placed at intervals along the length of the gravity zone continuously measure the reflectance of the sludge surface. PolyScan+ then calculates the drainage effectiveness by processing these measurements. The system automatically adjusts the sludge feed, polymer feed, and belt speed to achieve the best drainage at the lowest conditioning costs. Benefits include:
BASF Unveils New Polymer and Schedules Five Speeches at Stand 2613
At Booth 2613, BASF will unveil Zetag® ULTRA, a new cationic flocculant range offering high performance even in the toughest applications. BASF will also feature its new T-Rack® 3.0 based on Inge® ultrafiltration membrane technology for seawater desalination and wastewater reuse. In addition, attendees are invited to the booth for 15-minute presentations from BASF and Bob McIlvaine, President of the McIlvaine Company (schedule below).
“BASF is committed to providing sustainable solutions to address the world’s rising water demands,” said Linda Muroski, Business Director for BASF Water Solutions in North America. “Our extensive product portfolio of water treatment products, investment in R&D, and collective strength of our growing team is helping our customers meet their water management goals.”
The new products BASF will introduce at WEFTEC align with customer needs for improved water treatment solutions, such as high performance flocculants and membrane technologies. The Zetag® ULTRA flocculant range offers strong floc integrity for high shear applications and can be used in highly variable sludge conditions. It is especially effective for plants that use centrifuge, flotation and gravity belt thickener processes. It offers a significant dosing reduction compared to the market standard. As a result of its effectiveness, operational cost savings and a reduction in biosolids transport and landfill disposal costs can be achieved.
The T-Rack 3.0 is a compact ultrafiltration solution to address the specific requirements of larger-scale filtration systems such as those used for the pretreatment in seawater desalination or wastewater reuse. It meets the key requirements of corrosion resistance and high pressure operability at high temperatures and also supports greater treatment capacity. In addition, the T-Rack’s plug and play installation lowers the amount of maintenance required.

Today, roots aeration controls systems technology delivers customers savings of up to 40 percent of the energy used for WWT aeration.
GSM - Booth 253 has a range of belts for dewatering applications
Satin Weaves are the most commonly chosen fabric style for municipal sludge dewatering. Satin weaves offer high solids capture rates, good cake release, and fabric strength.
Spiral link fabrics offer superior fabric life and have the added benefit of no clipper seams. Spiral belts when assembled are essentially endless. Many municipal waste water plants are now using spirals for the top and bottom press zones and are particularly useful for older machines.
Plain weave fabrics are mostly used for very high drainage rates and are typically found on gravity tables in applications with very high coarse material sludge.
IDEX – Booth 1605
Waste water treatment is a principle area of application for Pulsafeeder’s hydraulically actuated diaphragm metering pumps. Not only is pollution control of waters being returned to the environment a necessity, but availability and cost of fresh water has made recycling of industrial process water necessary.
Pumps can be installed as a single unit or within an integrated system. With our extensive product knowledge and expertise in integration, we can supply our customers with the most efficient pumping technology available.
