Use "removeCartItem" function in your controller to do this...

function removeCartItem($rowid) {   
        $data = array(
            'rowid'   => $rowid,
            'qty'     => 0
        );

        $this->cart->update($data);
}

Create a remove button at view page and add row id with link. After that create a function and pass row id and put quantity 0 and pass that array in update function.

public function remove_cart_product($data) {
  $row_id=$data;
  $qty=0;
  $array=array('rowid' =>$row_id ,'qty'=>$qty );
  $this->cart->update($array);
  print_r($this->cart->contents());exit();
}

If the quantity is set to zero, the item will be removed from the cart.

$data = array(
           'rowid' => 'b99ccdf16028f015540f341130b6d8ec',
           'qty'   => 0
        );

$this->cart->update($data);

Here, set QTY = 0 then it will be removed.
