Walchem has introduced the Digital EZC Series Metering Pumps, the latest addition to its E Class pump line. The new pumps are solenoid-driven, diaphragm metering pumps with a maximum capacity of 6.7 gph and a maximum pressure of 150 psi. The high speed, fixed stroke length design makes the pumps an economical solution for applications requiring low cost but high turndown capabilities. The units pump at 360 strokes per minute, reducing the chemical slug feeding found in slower metering pumps. The digital controller has three pushbuttons for speed adjustment and provides an IP65 solution for harsh environments. For installations with restricted access, the digital controller can be mounted remote from the pump.

Wastewater analysis

Click here to enlarge image

Micro Dist® from Lachat is designed to avoid the costly problems of using expensive, fragile glassware, fume hoods, and clean up when distilling samples for wastewater analysis. The system distills up to 21 samples for sulfide, cyanide, methylmercury, and ammonia in 30 minutes, phenolics and tritium in 90 minutes. The system can handle many sample types, even if the sample is a sludge or has a high level of suspended solids. The USEPA has now approved Micro Dist analysis for NPDWR monitoring of cyanide and recommended approval for NPDES monitoring. The unit consists of only two pieces, a collection tube with a porous membrane and a sample tube, which are disposed of after use. The press fit joint between the two does not leak, a potential problem when using glassware.

The ecoSep® Below Grade Oil/Water Separator from Royal Environmental can help keep water clean from oil contaminates. The unit permanently separates oil from water and allows virtually no oil emulsion formations to develop. Independent testing demonstrates that its high-efficiency separation of free oils and hydrocarbon-laden sediment exceeds today's environmental standards. The units can be designed for use in point-source and industrial stormwater applications. No external energy supply is needed; there are no electrical parts, only mechanical and stainless steel components. The units allow for access to all major components for cleaning and maintenance.

Water treatment

USFilter Kruger Products' Actiflo system is a compact, high-rate, physical-chemical clarification process that uses microsand along with lamellar settling to enhance flocculation and clarification. By using microsand as a seed for floc formation and clarification, the process is up to 20 times smaller than conventional processes. Furthermore, the sand allows for more effective removal of solids, organics, metals and pathogens. The sand also stabilizes the process during sudden fluctuations in raw water quality.

Seawater treatment membranes

In response to demand for a less cumbersome and costly way to treat seawater for production of industrial process water, GE Osmonics has engineered the new Seasoft™ membrane elements. Using Seasoft nanofiltration (NF) elements as a pretreatment step reduces the hardness of seawater by more than 95 percent. This hardness reduction enables reverse osmosis (RO) plants to operate at lower pressures and higher recoveries. By providing a more purified feed to subsequent processes, the new membranes have facilitated a 25 percent increase in overall productivity while reducing pressure requirements by 17 percent. The membrane elements are available in a standard 8 in. diameter and 40 in. length.

Laboratory testing

Odor Control Co. is now offering free lab testing of malodor samples. The company will test the sample and formulate an odor neutralizer that will eliminate the odor problem. Its lab helps customers determine the best molecularly structured odor neutralizer for their waste. A wastewater treatment plant might identify hydrogen sulfide as their primary source of odor problems. However, there might be additional, less detectable or identifiable odors being emitted into the air. Raw sewage has pesticides, food preservatives and other chemicals that add odors into the air. As an added service, the company will provide and pay for a sample testing kit and all related shipping and testing charges.

Powder coatings

Atofina Chemicals reports that in recent cavitation erosion resistance tests, coatings of Rilsan® PA-11 fine powder were shown to be three times better than 316L stainless steel. In other cavitation tests, Rilsan coatings were over 75 times more cavitation erosion resistant that the best fusion-bonded epoxy coatings. All tests were conducted and reported by an independent testing laboratory. The fine powder coatings meet AWWA standard C224.01 and several different colors are approved for potable water use under NSF-61. They are easily applied using conventional powder coating methods and are available worldwide.

Gemco a manufacturer of equipment for solids processing industries, has manufactured its line of Spherical Disc Valves since the 1930's. While this valve offers a full port opening, self-cleaning seat and long life, it does require a high profile related to its diameter. For space restricted applications, the company now offers a low-profile Butterfly Valve. Measuring only 1 1/2 inches in thickness, the SB valve can fit in the tightest spaces.

Munox® XL-Plus, available from Osprey Biotechnics, is patented biotechnology using natural, live bacterial cultures for degradation and control of fats, oil & grease (FOG) prevalent at wastewater collection and transfer points. Treatment with the product is a safe, cost-effective method of eliminating troublesome organics from municipal treatment systems. Using the new grease treatment program, municipalities report 90% to 100% reductions in grease buildup at previously troublesome locations. The product recently gained recognition by EPA's Design for the Environment partnership program, the first involving an industrial cleaner/degreaser that bioremediates.

Power winches

Thern power winches are a versatile alternative to complicated overhead hoist systems. The winch can be mounted upside down to a support beam to raise and lower filter screens for periodic cleaning. Once out of the channel, the screen is held in a cleaning position by a tie-off cable. There are several mounting options to accommodate special plant considerations. Special rated motors and controls provide protection in corrosive or explosive environments.

Gas flow equalizer

USFilter has introduced the new Equa-Draw™ System engineered by Wallace & Tiernan Products. The system eliminates waste and reduces labor associated with traditional manifolding of vacuum regulators commonly used for water treatment gasses, such as chlorine, sulfur dioxide and ammonia. The patent pending system equalizes the gas that flows from several connected gas containers — all under vacuum for safety. The design eliminates the need for manually balancing the flow rates from each individual vacuum regulator. The modular system can link up to six gas containers, either 150 lb. cylinders or one-ton containers.
