System shall be designed to be naturally aspirating for benefit of biological treatment.

Wastewater treatment/recycling system shall function 100% automatically by use of a Programmable Logic Controller (PLC) and Data Logging System (DLS).  It shall be designed for continuous operation as needed. 

Wastewater Treatment/Recycling System Description

The wastewater treatment/recycling and wash waste water management system shall utilize the following technologies; solids pre-treatment, oil/water separation, dual media filtration and polishing.  The Wastewater treatment/recycling process filtration/polishing system shall be capable of remove particulates in the wash water down to one (1) micron, remove hydrocarbons, trace quantities of solvents, dissolved heavy metals and separate both free oils and emulsified oils from the water.  The Wastewater treatment/recycling wash waste water management process shall produce a treated effluent suitable for recycled water washing operations.

The treatment/recycling system shall be designed to function either as a closed-loop recycle system or approved pretreatment discharge to sanitary sewer.  Plumbing and PLC/DLS operations shall be engineered to accommodate either mode of operation depending upon the mission and location requirements.  Mode of operation shall be toggle switch selectable.

Solids Recovery Management System:

The wastewater treatment/recycling system shall include a solids recovery management system which  employs a "Solids Settling Tank" in combination with a Continuous Media Automatic Filtration Unit for active solids removal.  This Solids Management System is designed for removal of particulate solids down to 5 microns nominal.  It shall use a rayon filter media 18’ wide supplied in a 100-yard roll of 5-micron nominal filter media. 

The Continuous Media Automatic Filtration Unit shall be of stainless steel construction, incorporating an automatic filter media advance, cascade electrical float controls, auto discharge, integral spent filter media collection tray, and shall be factory assembled, installed and tested.  A lightweight removable, see-through cover shall be included and installed to capture water spray and provide visual observation of the process.

The Continuous Media Automatic Filtration shall operate in conjunction with an "SST" Solids Settling Tank.  Fluid from the wash pad shall be pumped to the "SST".  Fluid shall then be transferred from the SST to the Continuous Media Automatic Filtration solids filter then returned to the SST.  This is a continuous process of solids removal with volume through the system a function of process displacement.

Wastewater recycling  Polishing Filtration/Recycle System:

The Wastewater treatment/recycling system shall include a filtration/polishing recycle system to remove particulate solids down to 1-micron nominal and free oil levels down to less than 10-ppm.  The filtration/polishing system consists of three complete modules; 1) oil coalescing and active skimming; 2) a polishing loop for secondary solids recovery plus emulsified oil, hydrocarbon and solvent recovery; 3) a polishing loop for heavy metals removal.

Description of Wastewater Treatment/Recycling System Operation:

As effluent liquid from the solids recovery management system enters the filtration/polishing recycle system, it shall be slowed down through a quiescent tube to allow for solids to fall to the bottom of the coalescing tank where oil/water separation shall commence.  Free-floating oils are naturally transferred through a minimum 76,896 square inches of oil coalescing (oileophilic) plates.  These plates shall be self cleaning and slanted at 15 degrees, and constructed of high impact polycarbonate, allowing for oils to coalesce whereby they float to the surface and can be mechanically skimmed from the water. 

An active- oil belt skimmer (with oil/water decanter) shall be provided and used to collect the coalesced oils and discharge to an end user provided plastic storage bucket or similar containment for oil collection.   Virtually water free of oil shall then flow to a primary media polishing loop, which is designed to reduce light and emulsified hydrocarbons to less than 10 ppm and suspended solids to less than 1 micron.  A secondary media polishing loop shall be supplied using a filter media suitable for removal of dissolved heavy metals.

The Wastewater treatment/recycling system shall incorporate fully automatic backwash operation.  This removes contaminants from the polishing filter(s) and significantly extends life of the media.  Collected solids are returned to the wash pad sump area and subsequently to the solids management system for removal.

The Wastewater treatment/recycling system shall have the following features as a minimum:

Data Logging System Description

The DLS shall be owner programmable allowing programming of filtration system operational parameters using a touch screen; backwashing, system polish, day/date/clock, etc. The Adjust Hour buttons shall allow changes for daylight savings time.

The DLS shall include simple to navigate menus on a programmable touch screen that help guide changes to system parameters and controls.

Filtration system status messages shall be displayed during normal and energy saving operation. These messages shall include; ‘Polishing’, Energy Save Mode’, ‘Discharge to Drain’, ‘Backwashing’, and others required for complete operation of the system. Maintenance advisory and error messages shall also be displayed to assist with maintenance and service tasks as required.

The touch screen shall contain switch and indicator icons to be used in making changes  to the backwash settings. The backwash shall be programmable to commence on specific days and at specific times as prescribed by the owner. The touch screen shall include seven simulated LED’s showing the scheduled backwash days.

The touch screen shall include switch and indicator icons used to make changes to the System polishing settings. The filtration system shall produce maximum flow and the highest quality filtration when operated in the high polish mode.  The unit shall be programmable to operate in this mode during peak production hours and in the energy saving mode during off peak hours. Seven simulated LED’s shall be supplied which illuminate on the days where high polish irate s programmed to perform.

Remote Internet Access Web Application

The DLS system shall log all the filtration system logic controller input and output activity along with the filtration system operating states. The system shall transmit a log file nightly to a secure database at the monitoring station.  Software shall be supplied which parses and will perform an analyses of the data.

Trend analysis software shall be supplied which creates reports and graphs of the wastewater treatment/recycling system operation.  The data shall be designed to diagnose system problems and forecast unscheduled maintenance requirements. 

Any error that occurs is shall be logged.  An error notification message, shall be included in an updated data log, and shall be immediately sent to the monitoring station. The error shall analyzed by the software and If designated to do so, an ‘alert’ email messages shall be sent to the Owner’s service personnel.

The DLS combined with monitoring service shall; provide error notification, advise when it is time to replace consumables, provide a charting tool that allows the log of machine operation to be presented over various time periods, and provide a weekly summary reports via email.
