2. The 1st enviromentally-friendly filtering system
for the optician

3. Respect nature !
38 millions of lenses have been sold in France in 2017.
500 tons of particles have ended-up in sewage works.
m3 of drinking water have been poured into the drains.

4. Water and the Law !
The European community legislation authorizes discharges into the sewage system of loaded water up to 100 mg of particules per liter. Each lens edged generates about 13 g of particules.
To comply with the law, man would consume about 130 liters of water for each edged lens !!

5. The Law - Definition
Pollution of water can be associated to the presence of floating objects, coarse material and coarse particles in suspension.
Depending on the size, these particles are generally divided into :
Coarse material (settleable or floatable)
The suspension material (form oragnic or mineral nature) which are insoluble, fine.
Définition de la pollution par les matières en suspension – MES -

6. The Law - Values Measuring unit mg/litre Release limit value
100 mg/l if the stream does not exceed the maximum daily of 15 kg/d
35 mg/l if the stream exceeds the maximum daily of 15 Kg/j

7. The Law – Consequence This particulate pollution is the cause of
many issues related to material deposits,
their physico-chemical adsorption* capacity and damage to equipment by clogging, abrasion, etc. 
The main effect is the clouding of water ─ what we call turbidity ─ reducing the penetration of light rays that are indispensable to the regular growth of plant life on river beds.
*Adsorption: the adhesion of substances to the surface of a particle by a process of weak bonding.

8. The Law – and us ? Classification of waste particles due to grinding :
Grinding residus, not containing dangerous substances.

9. A filtering system that respects
the environment
the operator
the machine

10. Description Without water consumption, Without rejects,
Without odours,
Neptune filtering system enables opticians to supply water to their edger 
With the same efficiency as an open water circuit.
In complete conformity with legislation on waste water discharge.

11. Description Every day, 50 liters of clear water for Edging the lenses
Rinse and clean the machine
Improving the use of the machine
Neptune allows
A permanent re-use of the water
To aggregate the neutral residus than can be disposed in the domestic waste

12. Principle
Day
Night
During the work phase, it is the edger that drives the system. Neptune's job is to maintain a constant supply of water to the grinding wheels during operation.
In the filtering phase the edger is stopped and the cycle is driven by Neptune. Duration 6 to 8 hours. The cycle is executed while the store is closed.

14. Filtration Cycle -1- Transfer Water loaded with particles
Pump (1) starts, shakes all the "sludge" that has been deposited at the bottom of the work tank and sends the cooling water and grinding residue into the filtering tank

15. Filtration Cycle -2- Cleaning the work tank
As soon as the sensor (2) on the filtering tank has detected five litres of filtered water, the return pump (3) starts up and sends water under pressure through the nozzles on the top of the work tank to clean the sides
The pump (1) detecting the water, starts up and sends the cleaning water back to the filtering tank. 
Cleaning cycle lasts 60 minutes and is repeated up to 10 times.

16. The filtering bag has to be changed every 1500 lenses.
Filtration Cycle
-3- Filtering
Once the work tank is clean, pump (1) is deactivated. All the water is now in the filtering tank. Through gravity it is filtered through the disposable filter (4) where all the grinding residues are stored.
The filtering bag has to be changed every 1500 lenses.
It weights about 20 kgs

18. Anti-Smell Cycle Active principles
- Zinc Ricinoleate  Zinc Ricinoleate is a highly efficient deodorizing agent which neutralizes bad smells. It is used in both conventional and organic deodorizers
- Activ Carbon Active carbon is an inert microporous carbon with a broad internal surface (up to 1,500 m2/gramme). This surface can absorb organic molecules that occur in liquid and gaseous substances: polluting molecules adhere to it. The carbon (sourced from coal, coconut shell, wood, etc.) acts through a three-step process: the water is removed (dehydration); the organic matter is transformed into elementary carbon (carbonization) and the non-carbon elements are eliminated.

19. Buying motivation for the optician:
Look for savings
Ecological sense
Desire to fulfill the law
Cannot stand the decantation tank any longer
- manipulation, smell, overflow, standing water…
Need to decrease edging smell
Problems with limestone deposit
Plumbing blocked by residus
Need to move the equipement
To another floor
To basement
Temporarily
