Successful Screening Pilot At A Major Waste-To-Energy Player
Successful Screening Pilot At A Major Waste-To-Energy Player

Parkson recently had a very successful pilot test at the facility of a bio-feedstock supplier of waste products turned into fuel. The Rotoshear® unit, equipped with a .060” wedgewire screen, successfully removes solids directly from Industrial Waste Hauling trucks to recover grease. Screening this material before it enters the receiving station allows the facility to focus on proper treatment of the industrial wastewater rather than the expensive downtime to drain and clean their receiving pond.

WASTEWATER CASE STUDIES AND WHITEPAPERS

  • Case Study: Royal Environmental Systems And Water Tectonics Design State-Of-The-Art Stormwater Treatment System Located 20 miles east of Seattle, WA, Redmond is home to 50,000 residents and many high-tech and biomedical companies, including Microsoft. Redmond’s downtown drainage area is dominated by commercial, industrial, and roadway areas, with typical surface pavement contaminants such as metals, nutrients, and sediments. To help prevent stormwater runoff from harming local waterways, the city developed stringent stormwater regulations and sought a permanent stormwater treatment system that exceeded existing environmental guidelines

    Maximizing Your ROI On Test Equipment

    In today’s economic climate, it’s tempting to want to buy the cheapest test equipment you can now. But, how can you tell what the true cost of test equipment is? You have to consider how widely your water and chemical consumption will vary as the readings on your instrumentation does. By Heather Rekalske, Myron L Company

  • KLa Jet Aerators/Mixers For Large Diameter Equalization Tanks
    KLa Jet Aerators/Mixers For Large Diameter Equalization Tanks

    Many municipalities are facing the challenge of having to equalize large volumes of storm water sometimes mixed with raw sewage in order to continuously meet their permit limitations. The equalized flow is stored during a storm event and then slowly diverted to the treatment facility when influent flows return to normal levels.

  • How To Buy Right, Not Cheap When It Comes To Solids-Handling Pumps

    Companies using solids-handling pumps as part of their processes know that even though the pumps are typically moving trash and other waste products, the type of equipment used can be a huge business decision. Most applications warrant more attention than simply choosing the first pump that pops out of a catalogue. By The Gorman-Rupp Company

  • How To Select The Most Effective Blower Technology For Wastewater Applications
    How To Select The Most Effective Blower Technology For Wastewater Applications

    Given numerous variables when selecting an aeration blower system for wastewater applications, and equally numerous claims by technology providers, it is not surprising that confusion exists. Worse than confusion is the disappointment that results when a blower technology fails to perform as anticipated — and operating cost and efficiency benefits go unrealized.

  • Clarification System Boosts Capacity, Reduces Maintenance
    Clarification System Boosts Capacity, Reduces Maintenance

    Spikes in peak demand at the 3.0 MGD Freedom District Water Treatment Plant in Carroll County, MD, exceeded 70 percent of the plant’s capacity, and the existing clarifier made for a lengthy sludge-removal process. After staff installed a dissolved air flotation (DAF) pretreatment system to improve the efficiency of the membrane filters, the now 4.0 MGD facility has reduced maintenance for operators. The system also safeguards against pathogens that can pass through traditional sand/diatomaceous (S/D) filters.

WASTEWATER PRODUCTS

Hycor® Helixpress® Shaftless Spiral Dewatering Press Hycor® Helixpress® Shaftless Spiral Dewatering Press

The Helixpress® unit is the cost-effective solution for dewatering the screenings collected by any type of screen. It is an all-in-one conveyor, compactor and dewaterer. It utilizes a combination of drainage, compaction and dewatering to reduce weight and volume and ultimately decrease hauling and disposal costs.

Capital Controls® Series 71P11A Gas Pressure Reducing Valve Capital Controls® Series 71P11A Gas Pressure Reducing Valve

The Series 71P11A Gas Pressure Reducing and Shutoff Valve is a diaphragm-type gas pressure regulating valve designed for use on chlorine, sulfur dioxide and ammonia gas service. The valve is used in a gas dispensing system to prevent liquefaction of the gas by providing a controlled pressure drop in the piping system. Downstream pressure is regulated to a reduced value by adjustment of the control setting. If the downstream pressure exceeds the pressure at which the valve is set, gas flow will be shut off.

ecoSep  Below Grade Oil/Water Separator     ecoSep Below Grade Oil/Water Separator
ecoSep is a cost-effective below grade oil/water separation unit that can help keep water clean from oil contaminates
Pneumatic Dynamic Lifter Relief Valve Pneumatic Dynamic Lifter Relief Valve

The Pneumatic Dynamic Lifter is a very responsive compact wastewater relief valve that can handle high pressures and uses a compressed air cylinder to hold the valve closed. This chamber is fitted with a relief pilot that is normally closed as long as the line pressure is lower than the set point. If pressure rises above the set point, the relief pilot opens, causing the air in the cylinder to vent, which in turn opens the valve. The valve closes drip tight when pressure falls below the set point.

PCSWMM For Stormceptor Sizing Program PCSWMM For Stormceptor Sizing Program
PCSWMM for Stormceptor allows you to size the right Stormceptor System to achieve your stormwater quality objectives
MEMBRAY® NHP-Series MBR MEMBRAY® NHP-Series MBR

As part of Toray’s MEMBRAY MBR series, the NHP (New High Performance) module features thin membrane flat sheets that are densely packed into easily interchangeable cassettes. These cassettes allow for a higher packing density than what was originally thought possible with flat plate designs. The thin membranes are also highly flexible and allow for more movement, resulting in increased vibrations during aeration. This helps dislodge sludge and improve cleaning efficiency, all with less energy use.
