Isco's newest product is the Model 4501 Pump Station Flow Monitor. It is now easy to accurately measure the influent
flow at the pump station and the pump ing rate for each pump. Pump activity data is stored in the 4501's memory for later retrieval and analysis using a PC with Isco's Pumplink software. By de tecting abnormal pump activity, the 4501 can help conduct preventive maintenance before serious problems occur. Nortech Control Equipment,Inc.

Automatic wastewater
New metal-free
samplers
COD method
The BUHLER 1023 is one of a range of automatic wastewater samplers manufac tured under a Quality Management Sys
The Manganese III COD Method virtu ally eliminates disposal of hazardous metals waste. Patented Manganese III COD Reagents eliminate the use of char acteristic heavy metal oxidizers, catalysts and chloride removal agents, such as mercury, chromium and silver. In less than 90 minutes an analyst can complete up to 25 COD tests by using Hach's COD Reactor and colorimeter or spectrophotometer. A new specification sheet
tem that conforms to IS09001. The 1023
sampler is ideal for permanent installa tion at factories, wastewater treatment
plants, combined sewer overflows and river monitoring stations. It is a mainspowered refrigerated unit which can ac commodate various glass or plastic bot tle formats. An intelligent programmer is also provided to program the unit and to transfer and download data. A serial
link to a printer allows sample data to be printed on site. Cancoppas Ltd. For more information, circle reply card No. 191 56
Stormceptor Canada has introduced the
Preceptor™ line of fibreglass reinforced plastic (FRP) interceptors. Designed to effectively treat process wastewater con taining oil, grease, food waste and
settleable solids,Proceptor™ interceptors provide benefits beyond front line oil and solids separation. Their cylindrical de sign enhances hydrauhc performance and reduces the likelihood of resuspension during subsequent flows. Ideal for inter nal and external installation.
