NSG Precision Cells Releases New Suspended Solids Water Filtration System

Share Article

Suspended solids are materials that resist settling and remain suspended in water and other liquids. The ability to automatically concentrate suspended solids containing very-low concentration of microorganisms has been a troublesome task for scientists and researchers. Today this task is usually performed using Enviro-check cartridges, spending 6 hours for collection and then this process requires very complex process consisting of more than 20 steps prior to the concentrated samples of suspended solids could be analyzed in a lab. The CSS-3 filter released by NSG cuts this works in half.

NSG CSS-3 Automatic Suspended Solids Water Filter

The CSS-3 suspended solids filter is an automatic, maintenance free portable instrument for In-Situ concentrating microorganisms and other suspended solids from large volumes of water. The purpose of this is to allow scientists and researchers an easy was to analyze these solids in a laboratory.

Some microorganisms and other suspended solids in water have a very small
concentration (i.e. one instance of a microorganisms per 100 Gallons of water).
Therefore, capturing such suspended solids for the purpose of further analysis is a
very challenging process. The CSS-3 instrument addresses these challenges and the CSS-3 is the only instrument that is maintenance free and does not require any type of disposable filters or other parts.

What the CSS-3 filter does is it concentrates microorganisms and other
suspended solids contamination from a large user desirable volume of water (tenths,
hundreds and thousands of gallons). It automatically concentrates at least 98% of
suspended solids larger than 0.5 micron. The industry standard for this is currently 0.8 micron.

The CSS-3 does not separate concentrated microorganisms from other types of
concentrated suspended solids but rather concentrates them altogether. Users may inquire about custom versions of this instrument designed to separate suspended solids of different sizes.

The concentrated suspended solids can be easily removed from the CSS-3
instrument to a 1-Gallon bottle or bottle of choice by the researcher.

A unique feature of the CSS-3 instrument is while the CSS-3 instrument concentrates suspended solids, the suspended solids remain in suspension. The solids are not altered and they do not form sludge. This allows a user to remove the concentrated suspended solids’ solution in water from the CSS-3 instrument and analyze samples of the solution in a user’s lab by using other
user’s equipment.

High-efficiency in-situ concentration of suspended solids from a large volume of water is achieved through replacing traditional filtration methods with the fundamentally new proprietary technology for the purpose of preserving properties of suspended solids and preventing formation of sludge in the concentrated solution.

The CSS-3 is highly energy efficient. Less than 100 Watts of power is needed to process more than 2.5 gallons of water per minute, which is more than 125 gallons per hour.

The CSS-3 instrument can separate suspended solids from a source water
with extremely wide turbidity range – starting from 0.0001 NTU and up to at least
50 NTU.

The instrument is made for field-applications in the following user environments; 1. In rural environment (i.e. lakes and rivers) where there is access to 12V DC 10Amp
continues electric power (i.e. a car battery), 2. In a lab where there is access to standard 110 or 120 Volt AC power. 3. On a customer's site, which could be virtually any municipal, industrial, or a military site.

For the purpose of keeping the weight of the instrument as light as possible the
instrument does not have a typical instrumentation housing and instead is packed to the
light enclosure.

The CSS-3 instrument contains the following components:
1. Two pumps
2. Valves
3. Water flow-meter
4. Electric console
5. One input and one output short water pipes ½” I.D. with the hose-barbs.
6. The core-concentrator module
All the components mentioned above are mounted and connected by the manufacturer of
this instrument.

Technical specifications:
1. Electric power consumption: 12V DC 8.3 Amp continues power source or 110V AC -
120V AC 1.3 amp (with the included transformer 120 V AC/12V DC)
2. Water flow > 2.5 Gal per minute at input water turbidity 1 NTU
3. Concentrating suspended solids: at least 98% of suspended solids larger than 0.5

The instrument has three operating modes:
a. Concentrating at least 98% suspended solids from a source water. The processed water
where the said suspended solids have been removed could be used by user for various
purposes or safely disposed to the same water source because the instrument adds nothing
to water, with the exception of disposing the said processed water to a drinking water
source as a matter of precaution.
b. Rinsing
c. Disinfection

The instrument can be operated unattended for quite a long time (many hours or days,
depending on a source water turbidity). Because usually the source water turbidity as well as size and concentration of suspended solids in source water cannot be predicted, the instrument may automatically stop pumping water through which would require a user to remove the
concentrated suspended solids after few or several hours of concentrating the suspended
solids (for example, if input water turbidity exceeds 10 NTU, or after several days (for
example, if input water turbidity is 0.1 NTU) depending on the input water content.

Disposal of suspended solids is a fully automated process which is initiated by user and
takes less than 5 minutes.
