Jart Testert Analysis in Water

Jar test is an experiment that serves to determine the optimal dose of coagulant ( usually alum / alum ) used in the water treatment process. Jar Test is a water purification process using a coagulant, which coagulant will form a floc - floc with ions - ions contained in the sample solution. The floc-floc collect small particles and colloids that grow and eventually settle together.

Floc formed by the agitation of the agitator tool. With the concentration and volume of different coagulant to form a coagulant that is different and will certainly result in a different level of clarity. The coagulant is generally in the form of Al2 ( SO4 ) 3, but can also be a salt FeCl3 polylectrolytes or something organic.

Coagulation and coagulant

Coagulation is the process of adding chemicals to memebentuk blob ( floc ) were then separated on a flocculation process. While flocculation is a process to accelerate clotting particles with very slow stirring. Coagulation is a colloidal particle coagulation process for adding chemicals so that the particles are neutral and form deposits for their gravitational forces.

Broadly speaking floc formation mechanism consists of four stages, namely :

Stage destabilasi colloidal particles

Phase formation of colloidal particles

Phase merger mikroflok

Stage mikroflok formation.

Coagulation Mechanism In Physics

Heating à colloidal system temperature rise causes collisions between particles sol with water molecules increases this much.The release electrolyte adsorbed on the surface koloid. Akibatnya uncharged particles.

For example : blood.

1. Stirring, eg starch.

2. Cooling, ie that - that.

3. Coagulation Mechanism In Chemistry

In chemistry such as the addition of electrolytes, colloidal mixing different charge, and the addition of chemical substances koagulan.Ada several things that can cause the colloidal neutral,

namely :

1. Using the principle of electrophoresis à electrophoresis process is the movement of colloidal particles are charged to the electrode of opposite charge. When these particles reach the electrode, the colloidal system will lose its load and neutral.

2. Addition of colloidal à may occur as follows : negatively charged colloids will attract positive ions ( cations ), while the positively charged colloid will attract negative ions ( anions ). These ions will form a second layer sheath. If the second layer veil was too close to the same veil will neutralize the charge of colloids, causing coagulation. The greater the stronger ionic appeal with colloidal particles, so the faster the coagulation occurs.

3. The addition of electrolytes à If an electrolyte is added to the colloidal system, the colloidal particles will adsorb negatively charged colloids with a positive charge ( cations ) of the electrolyte. Likewise, the positive particles will adsorb negative particle ( anion ) of the electrolyte. Of adsorption above, coagulation occurs. In the process of coagulation, colloidal stability is very influential. Factors - Factors that affect coagulation and flocculation: water quality, water temperature, type of coagulant, a coagulant aid, water pH, the amount of dissolved salts in the water, raw water turbidity levels, stirring speed, stirring time and dose of coagulant.

Coagulants

Coagulant is a chemical that causes the destabilization of the negative charge of particles in suspension. This substance is a donor of positive charge are used to destabilize negatively charged particles. Coagulant is common and has been known which is used in water treatment
