LAKOS Waterworks PWC Series Separators Separator Operation LAKOS Separators are designed specifically to remove solids from liquids. Each model is calculated for use within a prescribed flow range for maximum performance and solids removal. Flow rates above and below the recommended range may affect such performance.

LAKOS Waterworks PWC Series Separators 1. LAKOS Separators are shipped on skids or in wooden crates. Support legs (22 ½° low profile models only) are detached and included with shipping. Lifting lugs, located on the unit’s side, are provided for hoisting as necessary. 2. A suitable foundation is necessary to accommodate the LAKOS Separator’s weight including liquid (see chart, page 4). Anchor bolts are recommended in the base of the legs (low profile) or skirt (vertical profile). 3.
LAKOS Waterworks PWC Series Separators Recommended Inlet and Outlet Piping The direction of inlet and outlet piping connections is important to minimize any potential effects from vibration. LAKOS recommends the following inlet & outlet piping connection configurations. Consult factory for other options if these piping configurations cannot be accommodated. Purging 1. LAKOS Separators must be purged regularly.
LAKOS Waterworks PWC Series Separators 5. To determine the necessary frequency, purge often at first and calculate the proper rate with regard to the actual volume of separated solids. Purge duration should be long enough to evacuate the purge chamber of solids. Frequency of purge should prevent the time it takes to fill the collection chamber more than approximately ⅓ its collection chamber capacity.
LAKOS Waterworks PWC Series Separators Trouble-shooting Guidelines for Separator Installations 1. Verify Actual Flow Rate: Use pressure gauges to indicate differential pressure and/or flow meter to verify flow rate. (Multiple pumps used to increase flow are installed in parallel (into common manifold); multiple pumps to increase pressure are installed in series (one after another)). Flow meters should be installed prior to the separator.
LAKOS Waterworks PWC Series Separators 6. Purging: Purge line piping should be as straight as possible to desired disposal destination. Avoid uphill piping, multiple elbows and low points where solids may accumulate and block the piping. Unless advised otherwise, do not reduce the piping size from that of the separator’s purge outlet size; restrictions can cause blockage and prevent proper purging of separated solids.

Air Relief Ports: The appropriate air relief ports should be used at start-up to expel air from the separator. If the separator will be drained periodically or exposed to entrained air or gases from the piping system, air vents should be permanently installed. 10. Down Stream Filtration: The use of finer filtration (polishing) downstream from the separator is a common application.
