There are also some precautions of the plastic crushing and washing, because of the different of plastic type, the processes of the plastic plastic are mainly separated to two types–hard material and soft material. Their washing and cleaning methed and equipment are certainly different.

In one hand, the waste crusher of soft material and hard material are different. Specifically, their blades are different. In the other hand, in the duration of the cleaning, the soft material like plastic woven bags are always floating on the surface of the water, we call them “flaoting material”, the hard plastic like PP flakes always sink under the water, we call them “sinking material”.

I jumla, plastiki ngumu ni safi zaidi na hutumia maji kidogo, hivyo hawahitaji tanki la sedimentation. (Tanki la sedimentation linaweza kupompa na kutumika tena baada ya maji machafu kukaa, ambayo itahifadhi maji kwa kiasi kikubwa.) Hata hivyo, vifaa vinavyosafiri juu ni vichafu sana, vina majivu mengi yanayozunguka juu yao na mahitaji ya maji ni makubwa.

Numera, många länder gör en förbud mot avloppsutsläpp, så bygg en sedimentationstank och muddfiltreringsutrustning, så kan vattnet i grunden uppfylla de nationella standarderna.
