24 Hour Remote Wastewater Sampling across 15 locations
Wastewater monitoring has become increasingly important in not only ensuring a producers consent compliance through automated quality checks , data logging and discharge ; but in an environment where there are increasing pressures socially , ethically and financially via increased economic penalties to adhere to set limits . It is a situation where a robust process has become essential .
Producers not only need the confidence of compliance in an era of increasing fines , but also reduce and limit any impact made upon the surrounding environment . Reducing the amount produced and tracing its exact origin can be a challenging prospect .
A customer contacted North Ridge Pumps with a requirement to remotely sample wastewater 24 hours a day , 7 days a week at set intervals across 15 locations . They needed to sample dirty water where water levels were very low at times meaning pumps were susceptible to dry running , there were fluctuating inlet pressures and a possible ingress of solids including grass , twigs and mud ruling out many pump technologies .
They needed a low maintenance solution to pump at very low pressures , with a flow requirement up to 500Lhour . Due to the remoteness of testing locations , and sampling required at various hours throughout the day they wanted to remotely control pump speed via a single-phase supply , have the ability to reverse units should they become clogged and have a way of detecting if the hose required replacement .
Our customer initially trialed a unit to check that the system performed as required , before ordering an additional 14 AMP16 3 / 4 ” Peristaltic Pumps complete with single phase inverter for speed control , hose leakage detector to enable the operator to know should the only wearing part fail via their installed PLC Controller , and with a remote input for reversing of the pump should any blockages occur . The units were supplied with forced air cooling allowing a wide operating flow with pump speed varying between 4 and 105 revolutions per minute .
As the pump supplied is of roller design they are expected to experience as much as 30 % reduction in unit power consumption compared to traditional designs of peristaltic pumps , extended hose life and see many years of troublefree service with inspection and lubrication intervals as much as 12 months apart .
If you have a wastewater treatment application and are unsure of the most appropriate solution , consult with us . As North Ridge Pumps are not tied to a specific pump technology we can select the most appropriate pump for your application .
