We provide superabsorbent polymers

The APROMUD® from APROTEK

The range of version of Apromud allow you to dry any kinds of sludge.  ADSORPTION AND ABSORPTION give a large field of use adapted to each industry

This super dryers solidify any liquid drilling muds, sludge contaminated and also save water in the concrete with increasing its specification.

 

THE SOLUTION FOR SLUDGE SLUDGE MANAGEMENT 

Keep the contaminent inside the sludge and let the nature have time to decompose it.

The SAP will give in 3 min sludge dry and allows you to excavate and re-use it in many way

Need to dig clean a pond or prepare fondation hole…. Think of Apromud

There is always an Aprotek solution for your case:

  • Industry,
  • hospital,
  • Agriculture 

Do you know the superabsorbent products?

Superabsorbent products exist on the market for over 50 years!

Originally developed in the USA for the purposes of agriculture and then quickly for the needs of the hygiene industry such as diapers.

They were able to replace natural products, such as peat moss, because the latter being a non-renewable source, was doomed to disappear. Various biosourcing initiatives in commodities having largely failed because of their poor performance, only polymers such as sodium polyacrylate and polyacrylamide are present on the market nowadays. World production is about 2 million tons today.

How do superabsorbent polymers work?

The polymer is composed of a long carbon chain regularly interconnected by bridges called « crosslinkers » channels, thus forming a network. Once the water is in contact with one of these channels, it is drawn into the molecule by osmosis. Water progresses rapidly within the network to be stored therein. Conversely, when the medium dries, the polymer then releases its water more or less rapidly.

Several parameters can affect the product: salt, temperature, UV … The life of the product, once hydrated, is a few days to several years depending on the type of polymer composition.

Field of use for Sodium SAP

  • Sludge management
  • Lagoon clearing,
  • construction site,
  • contaminated clearing sludge,
  • archaeological site
  • sludge excavation
  • damages due to flooding or fire are easier removed.
  • Drilling process optimization
  • Performances of bentonite clay
  • (the apromud series is boosting bentonite clay’s performances in order to reduce volume for transport and so cost time delay hazardous accident.)
  • Transport of hazardous waste or contaminated liquid

Why are there any variations in absorption according to the liquid level?

The first element is polymer chemistry itself. Depending on the amount used of the crosslinking, the polymer will absorb more or less liquid. For example, if the polymer is cross-linked, the network is thus narrowed and the stability over time is enhanced but the capacity is decreased. On the other hand, the less there is crosslinking the bigger the network is, so the volume of absorption is increased but stability is reduced.

Are super absorbent products degradable?

Once destabilised, when they have lost all of their effectiveness, « oligomers » (fractions of polymers) are formed. These elements, under thermal and bacterial action, mineralise at 8% the first year and then 3% per year in the ground, so about 30 years for total soil mineralization and digestion.

Recent studies on sodium polyacrylate demonstrate the biodegradable faculties of superabsorbent polymers under certain conditions.

APPLICATIONS :

  1. ENVIRONNEMENT – CONSTRUCTION

To facilitate sludge thickening, confinement, excavation

Drilling process optimisation

Boost performances of bentonite clay

Transport of hazardous waste / contaminated liquid

  1. Dredging operations– SEDIMENTS
  2. Slurries excavation– SEDIMENTS
  3. Management of ship bottom sludge
  4. OTHER SLUDGE MANAGEMENT: Drilling cuts => Sludge from concrete centrals=>Truck cement mixer (concrete excess)
  5. Bituminous sludge

The APROSOIL Series products for Agriculture improvements:

Save the water !
Save the planet !
Save you !

The advantages:  Acting as a water retainer for plants and soils, the superabsorbent products will undertake water absorption and loose cycles in the soil. Only a small amount of APROSOIL products mixed with the substrate result in optimal humidity conditions.

Ex: of APROSOIL application :

Agricultural crop, forestry and arboreal plantation, dust control in wood or husbandry  APROSOIL is highly recommended for any water saving objective.

SAP powder can:

– Improves seed germination and germination, giving plants an early, healthy start;

– Contains 18.3% Potassium and effective slow release of fertilizer;

– Save irrigation water and improve soil water holding capacity by 85% (for sand);

– Increase crop and fruit yield by 70%.

Mechanism of action

SAP powder for agricultural use is composed of a set of polymer chains parallel to each other and frequently linked together by cross-linking agents, thus forming a network.

When water comes into contact with one of these chains, it is drawn into the molecule by osmosis. Water quickly moves inside the polymer network where it is stored. That’s how SAP powder turns into water gel.

Since this water gel has a greater absorption capacity than soil but less than plant roots, the water absorbed by SAP will be released to the plant as it dries.

Advice:

The specific retention of SAP agriculture is 1.3-1.4 MPa, and the specific retention rate of the roots is about 1.6-1.7 MPa.

The APROCABLE Series products for Cable users/makers

 

It makes the waterproofness of both cables and optic fibers and thus enhance their life expectancy. It’s support the reduction of debit loss while protecting the cables of any water infiltration.

Examples of APROCABLESeries application :

there are always some degradation on cables due to some cuts or tears. Therefore, liquid can get inside and damage the cable’s efficiency, especially if the liquid infiltrates in the length of the cable. APROCABLE will act as a barrier as soon as the liquid will tempt to enter the cable.
