Launder covers

Pennwell web 300 193

NEFCO's Launder Cover Systems have been designed specifically to inhibit the growth of algae on the launder trough and weir surfaces by blocking sunlight from striking those areas. Without sunlight, the algae is largely eliminated or reduced to a light film that is easily washed away with a hose. It is estimated that more than 80% of the odors in the clarifier are produced when the effluent breaks over the weir. The covers are designed to contain these odors to prevent them from creating a nuisance and/or operate in conjunction with scrubber systems that draw the trapped gases off and treat them.

Coarse screen separator

Pennwell web 250 175

The Hydro-Sludge™ Screen is a horizontal in-line pressurized device that screens coarse solids from sludge and dewaters the material in a single operation. The enclosed system reduces odor problems and requires no washwater for cleaning. The coarse material retained on the perforated screen surface is transported to the pressing zone and onward to the outlet by a heavy-duty screw. Screenings are compacted by backpressure against the pressing cone and discharge into a container located below. The system is operated by a PLC control panel that allows for easy adjustment and operation. The Hydro-Sludge™ Screen can be used on both pump fed sludge or on direct discharge from a septic truck in primary, secondary, or combined sludges.

A new defoaming liquid, Microcat®-DF, has been introduced by Bioscience. The synthetic material can be used in aeration tanks, sludge digesters and other wastewater treatment plant apparatus to suppress foam without inhibiting the biomass or other side effects of conventional defoamers. Because it does not contain silicones, mineral oil, nitrogen or phosphorus compounds, it is compatible with all Microcat microbial-enzyme formulations and with naturally occurring biomass.
