Sludge reduction

Premier Wastewater International's Enhanced Solids Reduction (ESR) process reduces the need for wasting of organic sludge. The ESR process features a novel aeration/conditioning device that aggressively modifies the waste in such a way that it develops a coefficient of decay significantly higher than conventional systems. This increased efficiency permits a small-footprint plant that costs less to install and operate, uses no chemicals, eliminates odors and is very quiet.

Thern davit cranes and hoists, equipped with a quick-disconnect feature, can be used to simplify the task of placing and pulling pumps. The quick-disconnect allows operators to remove the cable from the hoist while leaving it attached to the submerged pump. The hoists are portable and can be moved from station to station and fitted into fixed bases. They are constructed with corrosion resistant finishes, galvanized or stainless steel throughout.

The new CR200 series wireless sensor/datalogger from Campbell Scientific provides a low-cost, wireless sensor interface by combining measurement I/O with a 900 MHz spread spectrum radio or with a CDPD digital cell phone. In CSO or SSO monitoring applications, sensor/CR200 combinations are deployed inside the manhole in a NEMA 6P enclosure. The system makes measurements and transmits data to a fixed base station (either a datalogger or computer) or to a mobile station, such as a laptop in a vehicle.

Rotary vacuum filter

The Auto-Vac filter from Alar Engineering will remove virtually all suspended solids from liquid slurries. It is self-cleaning with every revolution; it never blinds. With the aid of a diatomaceous earth filter media, solid particles as small as 0.5 micron are removed from the liquid being filtered. The solids are continuously removed from the surface of the filter media by a Stellite Knife blade and then deposited into a receptacle for disposal. The filters can be used to dewater sludges, greatly reducing hauling costs.

Multi-parameter monitor

The most important parameters in wastewater, dissolved oxygen, pH, conductivity, turbidity and suspended solids, can now be measured with one simple system, IQ Sensor Net. The system combines WTW's 50 years of experience in sensor design with a modern digital communication system. Each sensor performs all the necessary A/D conversions at the sensor site. Communication back to the transmitter is digital, allowing for cable lengths up to 3000 feet without amplification. More importantly, any combination of sensors can be connected into one IQ Sensor Net system.
