Product Description

EVU LAMELLA CLARIFIER

HOW DOES IT WORK?

The Lamella clarifier works when a solid/liquid stream that has been flocculated, enters a tank, and flows upward between a pack of inclined plates. The solids fall to the plate surface, where they slide by gravity down to a sludge collection hopper. The clarified effluent flows through orifice holes and exits the top of the settler.

CLARIFIER FAQ'S

What type of routine maintenance is needed for a clarifier?

Maintenance for a clarifier is minimal.  There are few moving parts, if any.  Metering pumps for flocculation as well as the mixer should be inspected and maintained according to the OEM guidelines.  The clarifier itself will only require and occasional clean out by draining the unit and hosing off any residual sludge at the plate packs and in the cone(s).  If the sludge is pumped out regularly, as needed, without allowing the sludge of override the plate pack, this will seldom be required.

 

Will a clarifier remove grease and oil?

It is best to remove oil and grease before sending a waste stream to the clarifier.  The EVU clarifier is equipped with an outlet skimmer that will hold captive a small amount of free oil, but this is only a safety net for a small amount of oil the was not properly removed.  The operator will need to skim off any oil that is captured by this skimmer.

 

Do I need to replace the plate pack on my clarifier?

Normally the plate pack will only be damaged when someone attempts to walk on the plate pack and physically breaks it.  Over time and depending on the chemistry involved, it may become brittle, but should not break unless abused.

What is retention time and hydraulic loading?

The two most important aspects of any clarifier are; retention time and the surface area (hydraulic loading).  Retention time is the time required for a drop of water to flow from the inlet to the outlet.  The greater the retention time, the longer the water will stay in the clarifier (the slower the flow rate) and the more time the solids will have to settle out.  A proper minimum retention time will be 50-60 minutes.Hydraulic loading is the relationship between the effective surface area to the flow rate.  A typical Met-Chem hydraulic load would be 0.2 GPM of flow to every square foot of surface area offered in the plate pack.
