System controls are critical to a wastewater blower system. Without them, a system with multiple blowers operating on their individual controls will run more than necessary and result in wasted energy. Maintenance costs increase and worst of all: process performance suffers.
Ten years ago, KLa Systems was presented with the challenge of finding a more wear-resistant material for our jet aeration nozzles. The inner nozzle is the liquid propulsion nozzle of the jet aerator and continuously sees high volumes of motive liquid flow at velocities ranging from 33-46 ft/s. Traditionally, these inner jet nozzles were made from the same FRP material as the outer jet with the industry accepted corrosion/abrasion liner made up of C-Glass/Nexus and Silicon Carbide impregnated into the vinylester resin. For many years this material had held up in most industrial and municipal bioprocesses with no adverse deterioration or wear.
The Thermatel® Model TA2 thermal mass flow transmitter, based on thermal dispersion technology, provides reliable mass measurement for air and gas flow applications.
Sauereisen SewerGard Industrial No. 210 is a novolac epoxy that is specifically formulated for industrial wastewater environments where plants and refineries treat contaminated water before it is sent to a municipal wastewater treatment plant.
The disc diffuser ROEFLEX® stands out for its simple and robust design. It consists of a unique, convex shaped support disc. The disc is covered by a flexible, slotted membrane of elastomer, a ring secures the membrane in place. Due to the disc’s unique convex shape the membrane is slightly lifted off the disc when air is supplied, therefore allowing an even distribution of the generated fine bubbles. The membrane can be delivered in different rubber (EPDM) qualities and slot patterns (HL, SL) according to the application.
