DESCRIPTION

A New Generation of Filtration Systems Offering Greater Savings and Efficiencies (Conserves up to 90% of Processed Water)

The AENVIRO Centrifugal Separator and system manufactured by AENVIRO for Fuidyne Int'l Corp. is a new-generation precisely engineered filter system for
high rise buildings. The Separator itself has no motorized parts, uses no chemicals or filter media, requires minimal scheduled maintenance (occasional
purging), and does not require backwashing. This Separator can be supplied as a complete system with suction strainer (as required), pump, solids purging system and/or filter bag housing, and NEMA rated control panel - or as a stand-alone unit for retrofit to other inefficient systems. The filtration system is designed to remove solids with a specific gravity range higher than 1.5, solids spherical
size - greater than 25 microns (25 micrometers) and solids concentration from 2% by weight. The AENVIRO "Velocentrifugation Process" of solids/liquids separation maximizes the use of fluid velocity through modified G-forces while minimizing the need for energy in reclaiming cleaner water. Fabricated
using all welded carbon and/or stainless steel construction and is a centrifugal vortex- style with tangential inlet capable of passing a solid with aspherical size equal to 25% of the connection pipe size without obstructing the path of the separation. The AENVIRO Separator is supplied pre-finished in a powder coated blue/green color.

FEATURES AND BENEFITS OF PARTS & COMPONENTS

  1. Fluid and solids contaminants enter tangentially
    through a cupped-type accelerator inlet exhibiting
    higher g-forces to the fluid and contaminants. A helical anti-collision plate is positioned in front of the inlet to prevent rotating fluid to hit the incoming fluid, thus preventing fluid hammering and vibration. Diffuser plates are also positioned to break clustered solids in the entering fluid. Guide skirt at the bottom of the discharge pipe, prevents solids from returning.
  2. The downward spiral motion causes high centrifugal forces to pull solid particles heavier than water out towards walls which then move down towards a
    collection chamber at the bottom of the separator.
  3. A set of circular vanes are positioned clockwise to ease the settling of the contaminants and preventing them from returning to the stream.
  4. Gravity pulls solids down into Separator collection chamber that holds a minimum of 4% solids by weight.
  5. The clean water or process fluid then rises up via a central vortex and top spin plate and through the system once again. The vacuum formed on top of the 'mushroom' spin plate is sufficient to accommodate another type of ozone treatment system that could be mixed in the returning cleaner vortex.

SYSTEM OPTIONS

Solids Purging Options:

APU-Auto Purge Unit:

Provides intermittent release of water or other liquid and contaminants to drain.

APU Auto Purge Unit

 

MPS-Manual Purge System:

Requires availability of staff to remove purgings.

MPS Manual Purge System

 

CRRS -Closed Recovery and Recirculation System:

Filtered water returns to system and collected contaminants are removed periodicallyvia a filter bag housing and an alarm set to signal if higher differential pressure across system is occurring.

CRRS - Closed Recovery and Recirculation System

 

Filtration Option:

Side stream filtration does the job of full stream filtration via multiple passes and is recommended for new filtration installations since side stream uses much less energy and is less costly in terms of capital investment. At the same time Fluidyine Int'l Corp. products/systems are equally adaptable to full stream systems in existing installations.

Sump or Basin Sweeper System Option

Using PVC and/or steel piping manifolds with molded thermoplastic or cast steel venturi-type eductors, the kinetic energy of liquid flow is utilized in agitating the solid contaminants towards the filtration system. Formation of hard scale and
settling of other solid contaminants are prevented, thereby improving cooling tower performance, minimizing downtime and maintenance while creating an improved healthy environment in areas surrounding the water cooling system.

SPECIAL FEATURES

Relavitely short pay back; upgrading to Fluidyne technology can deliver energy, maintenance, and down- time savings, and improved health.

LEED investment; aids in identifying green performance targets including AIR, ENERGY, WATER (LEED points).Recycling and re-use lends itself to sustainable building.

Conserves up to 90% water based on annual use; high cleaning efficiency eliminates contamination up to 98% of solids with specific gravity of 1.5% down to 45 microns. Minimize/prevents growth of bacteria.

Reduced power requirement; lower differentia power reduces energy requirements and increases heat transfer efficiency.

Substantially reduced environmental impact; virtually eliminates pollution resulting from chemical into air via discharge, slips, spray and drift. No solids or chemicals can enter into sewer system. Note: APU Auto Purge Unit requires solids disposal receptacle.

Protects equipment from early deterioration and foul- ing problems by separating solids e.g. sand, scale, rust, biofilm, grease, and floating orgaincs from supply water or other liquids. Keeps cooling tower basins clean with the use of sweeper system. Extends lifespan.

Optimum sound and vibration control; smooth filtration flow eliminates aggravating structure-borne noise, and pipe hammering.

Largest solids collection chamber available on market; also ensures smooth evacuation of solids.

Prevents reversal of solids; top spin plates, multiple spin arrestors and contoured solids settling vanes prevent contaminants from moving back to separator.

Minimal scheduled maintenance required; separator contains no moving parts to wear out or replace and does not require chemicals and other consumables. Only occasional removal of solids (system purge) is required via an annunciator feature mounted on the filter bag housing on CRRS models.
