LINT TRAP
INTRODUCTION
RSK-LT lint traps are standard compliant:
Uniform Plumbing Code (UPC)
ADVANTAGES
APPLICATION
The wastewater produced in laundries are full of lint and sands that interfere with drainage systems and sewage treatment.
DESIGN & OPERATION
The RSK-LT is designed to remove sediment, sand and lint from wastewater.
Lint Traps prevent sediment, sand and lint from entering plumbing systems to prevent clogging.
Primarily located right after laundry or on drain lines connected to central laundries, properly located and maintained interceptors keep drain systems free of problematic lint buildup.
The interception process is carried out through successive barriers that prevent the passage of suspended materials in the water.
The size of the product is estimated by the number of washing machines.

MATERIALS
For good general corrosion resistance and stability against intracrystalline corrosion effects of the various steels listed in the EN 10088-1, EN 10088-2 and EN 10088-3, only used austenitic steels (304L - 316L)
Interceptor bodies are 11 ga. cold rolled steel, with an oven cured, acid resistant baked grey epoxy coating, inside and out. Standard cover is epoxy coated.
Engineering Specification
FLOW CONTROL FITTING:
Flow control fittings ensure 90% or more retention efficiency of the interceptor.
When consideration isn’t given to the flow rate of the waste water to be handled, the actual flow rate through the interceptor usually exceeds its rated maximum.
With such flow rate, the interceptor would be overloaded. Retention time within the unit would not be sufficient for maximum separation.
The result would be low efficiency, and pollutants left in the waste water would pass through the interceptor, making the installation less than effective.
When the flow is controlled by use of a flow control fitting so that it can never exceed the maximum rating of the interceptor, and the interceptor is cleaned on a regular basis, the maximum pollutant retention efficiency will be achieved and maintained.
All flow control fittings are built with an air intake and should be connected to the vent stack or vent not lower than the flow level of the highest drain serviced or terminated in a return bend at the same elevation outside of the building.
A vented flow control fitting improves the efficiency of the grease interceptor by introducing air into the body of the interceptor.

Installation considerations
flow control
ventilation
Traps shall have ventilation holes, sized to comply with code requirements for venting traps to retain a water seal and prevent excessive pressure within the trap.
Multiple unit installation
It is recommended to use one device to service multiple installations only when the installations are close to each other. In such installations, each unit must be individually enclosed and rear ventilated.
MAINTENANCE
GENERAL CONSIDERATIONS:
To obtain optimum operating efficiency of a properly sized and installed interceptor, a regular schedule of maintenance must be adhered.
Interceptors are furnished with manufacturer’s operating and maintenance instructions, which must be followed to ensure efficient satisfactory operation.
CLEANING:
All interceptors must be cleaned regularly. The frequency of lint removal is dependent upon the capacity of the interceptor and the quantity of lint in the waste water.
Lint removal intervals may therefore vary from once a week to once in several weeks.
When the lint removal interval has been determined for a specific installation, regular cleaning at that interval is necessary to maintain the rated efficiency of the interceptor.
After the accumulated lint and obstructions has been removed, the interceptor should be thoroughly checked to make certain that inlet, outlet and air relief ports are clear of obstructions.
DISPOSITION OF INTERCEPTED MATERIALS:
The waste matter that has been removed from the interceptor should not be introduced into any drain, sewer, or natural body of water.
This waste matter should be placed in proper containers for disposal.
