The Perk Filter captures <br /> and retains sediment,oils, rr�etals and other target constituents close to the source ar�d reduces the#otal <br /> disc�arge load. <br /> The PerK Fi{ter cartridge is man�factured from d�rabfe polymeric cor�ponents with a <br /> polymer-coated steel support screen and stainless steel hardware. Its base canstruction <br /> allows use with a wide�ariety of inedia chosen to address site-specific pol{utants of eoncern. <br /> Perk Fiit�rs rr►ay be installed as a retrafit to suitable existing curb'tnlet, drop inlet,or combittation catch <br /> basins, as an in#egraE part af a coaied steel-or concrete-housed stormwater inlet system for corr�mercial, <br /> residenfial, and industrial de�elopments, or as centralized mod�lar treatrnent system installed either on- <br /> line or of#-line. <br /> Prefiltration <br /> Systems cansiructed with a catch basin inlet are equipped with a�IoGard�Plus Catch Basin Insert#or <br /> pre-filfration.�'his insert captures grass pollutants such as trash, debris, hydrocarbans, and large <br /> sediment particles. <br /> Gra�ity Separatior� <br /> Sorr�e Perk Filter systems have an inlet 6ay wherein the initial stormwater flows are received.This is <br /> separated from the r�-�ain treatment chamber by a batfle walE with weir assembly. Medium size sedi�nen# <br /> particles are retained in the i€�let bay. A drain down assernbly to eliminate standing water from the inlet <br /> bay area between storm events is included in standard configurations. <br /> Media Filtration <br /> Once the stormwater enters the treat�nent chamber, it will pass thraugh the filtration cartridges containing <br /> the project-specified filter rr�edia as the water level rises in the chamber. Very fine pollutant particulates <br /> will be refained in the filter cariridges as the water flows through the media to an interior perforated pipe, <br /> dropping the treated stormwater into an outlet char►�ber below a false floor. <br /> Peak Flow Bypass <br /> Perk�ilter systems are design�d with a peak flow bypass to ens�re the system will not back up and <br /> cause upstream flooding cl�aring extraordinary storm e�ents.�'he bypass weir is an integral part of the <br /> baffle wall assembly in the inlet bay and allows peak flow stormwater directly to the outlet chamber. <br /> , <br /> �d � <br /> , <br /> �_ ,,� � . _. <br /> y _ <br /> � <br /> =:�,_'�r��:�a W g_ <br /> r.ew� <br /> _„�;. <br /> �;,;:;`_-,:.' <br /> �-... <br /> :,; ,:.;�.,- <br /> _�ti;°�:w:�.<t;�.�w�x., <br /> �W g. <br /> ''°°�'��:� <br /> ��� � � <br /> � �, � J. <br /> � <br /> ' �°�,s��='���x�'` ma' ti",;;� <br /> z�;�:���""�t-�-�:� � <br /> ��,��.w:�s��:.�.:-� �.� <br /> ���._-.,� ��......• �:�; <br /> ��������, <br /> KsiStar Enterprises,lnc. <br /> 3605uiton Place <br /> Santa Rosa,CA 95A07 � <br /> (800)579-8819 <br /> www.kristar.cnm <br />
